Aims : This work aims at investigating the molecular and infrared components in the massive young stellar object ( MYSO ) candidate IRAS 18544+0112 .
The purpose is to determine the nature and the origin of this infrared source .

Methods : To analyze the molecular gas towards IRAS 18544+0112 , we have carried out observations in a 90 ^ { \prime \prime } \times 90 ^ { \prime \prime } region around l = 34 \aas@@fstack { \circ } 69 , b = –0 \aas@@fstack { \circ } 65 , using the Atacama Submillimeter Telescope Experiment ( ASTE ) in the ^ { 12 } CO J=3–2 , ^ { 13 } CO J=3–2 , HCO ^ { + } J=4–3 and CS J=7–6 lines with an angular resolution of 22 ^ { \prime \prime } .
The infrared emission in the area has been analyzed using 2MASS and Spitzer public data .

Results : From the molecular analysis , we find self-absorbed ^ { 12 } CO J=3–2 profiles , which are typical in star forming regions , but we do not find any evidence of outflow activity .
Moreover , we do not detect either HCO ^ { + } J=4–3 or CS J=7–6 in the region , which are species normally enhanced in molecular outflows and high density envelopes .
The ^ { 12 } CO J=3–2 emission profile suggests the presence of expanding gas in the region .
The Spitzer images reveal that the infrared source has a conspicuous extended emission bright at 8 \mu m with an evident shell-like morphology of \sim 1 \aas@@fstack { \prime } 5 in size ( \sim 1.4 pc at the proposed distance of 3 kpc ) that encircles the 24 \mu m emission .
The non-detection of ionized gas related to IRAS 18544+0112 together with the fact that it is still embedded in a molecular clump suggest that IRAS 18544+0112 has not reached the UCHII region stage yet .
Based on near infrared photometry we search for YSO candidates in the region and propos that 2MASS 18565878+0116233 is the infrared point source associated with IRAS 18544+0112 .
Finally , we suggest that the expansion of a larger nearby HII region , G034.8 - 0.7 , might be related to the formation of IRAS 18544+0112 .
